What is the most effective heat exchanger?
Plate exchanger is the most efficient due to turbulent flow on both sides.
High heat-transfer coefficient and high turbulence due to even flow distribution are important.
However, a plate heat exchanger regenerator is restricted to low viscosities.
With high viscosities, a special tubular may be required..
Is boiler a heat exchanger?
A boiler works by using hot gas to heat water – and a heat exchanger is what allows this to happen. … A condensing gas boiler is able to recycle this heat from the waste gases and use it to heat the water. Condensing gas combi boilers used to have two heat exchangers, as it’s thought that this was more efficient.
What is the difference between evaporator and condenser?
While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid.
Do I need a heat exchanger?
Within industrial plants and factories heat exchangers are required to keep machinery, chemicals, water, gas, and other substances within a safe operating temperature.
How much does a heat exchanger cost?
The cost of replacing a heat exchanger ranges from $2,000 to $3,500. Replacing your furnace’s heat exchanger would be a good route to take if your furnace is fairly new. However, it is not worth spending your money on replacing your furnace when it is near the end of its life span, which is ten years or more.
What are the types of heat exchanger?
Types of Heat ExchangersShell and tube heat exchangers.Double pipe heat exchangers.Plate heat exchangers.Condensers, evaporators, and boilers.
What is the difference between heat exchanger and evaporator?
Evaporator is the machine inside the air conditioner. Heat exchanger is the machine outside the air conditioner. If heating, exchange the internal and external machines.
How do I choose a heat exchanger?
The following criteria can help in selecting the type of heat exchanger best suited for a given process:Application (i.e. sensible vapor or liquid, condensing or boiling)Operating pressures & temperatures (including startup, shutdown, normal & process upset conditions)More items…
How many types of exchangers are there?
The two main types are finned and unfinned tubular. With a finned tubular heat exchanger, both fluids are unmixed, the one between the fins is guided in a direction transverse to the tube flow direction. In the unfinned exchanger heat can be exchanged in all directions, and the fluid can mix.
Is refrigerator a heat exchanger?
A heat exchanger is used to transfer energy from the inside of the refrigerator to the cold refrigerant. … The refrigerant is then passed through a heat exchanger (often coils at the back of the refrigerator) so that energy is transferred from the refrigerant to the surroundings.
How does heat exchangers work?
Heat exchangers, metal shells and tubes, work by transferring heat from one place to another. When a furnace burns natural gas or propane fuel, its exhaust/combustion by-products (also known as flue gas) enter and travel through the heat exchanger.
What type of heat exchanger is a condenser?
It is a shell and tube heat exchanger installed at the outlet of every steam turbine in thermal power stations. Commonly, the cooling water flows through the tube side and the steam enters the shell side where the condensation occurs on the outside of the heat transfer tubes.
What is the purpose of a heat exchanger?
Put simply, a heat exchanger is a device which transfers heat from one medium to another, a Hydraulic Oil Cooler or example will remove heat from hot oil by using cold water or air. Alternatively a Swimming Pool Heat Exchanger uses hot water from a boiler or solar heated water circuit to heat the pool water.
What are the two types of heat?
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.
What is effective heat exchanger?
Effectiveness of a heat exchanger. The effectiveness (ϵ) of a heat exchanger is defined as the ratio of the actual heat transfer to the maximum possible heat transfer.
What is the principle of evaporator?
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.
What are the three basic types of condensers?
There are three main types: air-cooled, evaporative, and water-cooled condensers.
Which type of heat exchanger is best?
The parallel-flow heat exchanger is the most suitable one if the area is an important parameter where as the counter-flow heat exchanger for the maximum net gain. The maximum net gains for all heat exchanger types are given in Table 3.
